Problems solved by technology

However, its amorphous formation ability is still limited, and its saturation magnetization is lower than that of traditional silicon steel alloys. After annealing and crystallization, although the saturation magnetization and magnetic permeability are improved, the two crystallization temperature ranges of the alloy are too narrow, and the amorphous phase Low Curie temperature, defects such as material becoming brittle after crystallization limit the high temperature application of materials
In addition, iron-based amorphous alloys lack room temperature plasticity, and the material is prone to brittle fracture

Description

technical field [0001] The invention relates to the field of electromagnetic device components of a mine magnetic separator, in particular to an electromagnetic block for the electromagnetic device. Background technique [0002] In the electromagnetic magnetic separator for ore dressing, the electromagnetic device is the part that consumes the most energy. In the electromagnetic device, the electromagnetic performance of the electromagnetic block affects the magnetic field strength generated by the electromagnetic device after electrification. The electromagnetic block of the existing electromagnetic block The performances are not ideal. In the case of consuming more electric energy, the strength of the magnetic field generated by it will decline with the prolongation of the use time, which will lead to the degradation of the performance of the electromagnetic device. The reason is that the metallographic structure and corrosion resistance of the electromagnetic block lead t...
